We are running Exchange 2010. When I try to create besadmin account and assign access/send as permissions it to all users, I get "Cannot process argument transformation on parameter 'Identity'" message. Here is the result: [PS] C:\Windows\system32>Get-MailboxDatabase | Add-ADPermission -User "BESAdmin" -AccessRights ExtendedRight -ExtendedRi ghtsReceive-As, ms-Exch-Store-Admin Cannot process argument transformation on parameter 'Identity'. Cannot convert the "System.Collections.ArrayList" value of type "System.Collections.ArrayList" to type "Microsoft.Exchange.Configuration.Tasks.ADRawEntryIdParameter". + CategoryInfo : InvalidData: ( [Add-ADPermission], ParameterBindin...mationException + FullyQualifiedErrorId : ParameterArgumentTransformationError,Add-ADPermission What do I miss? or which parameter 'Identity' do I need to add it to the command?

Your command matches the one I have in my notes. Is this a flat domain, or are child domains involved? Simon.Simon Butler, Exchange MVP Blog | Exchange Resources

This is what I did when moved to 2007. take a look at Blackberry: KB12483 & KB14502 add-exchangeadministrator besadmin -role ViewOnlyAdmin get-mailboxserver exch07 | add-adpermission -user besadmin -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin also I had to do this on a 2003 DC http://support.microsoft.com/kb/907434 not sure if you have to do this on a 2008

The commands for Exchange 2010 are slightly different. If you get the BES 5.02 installation instructions from RIM's web site, it outlines all of the commands that are required. The view only admin command is different for example. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources

Thank you for all inputs. My problem is I copied the command line and pasted it. However, there is not a space between "ExtendedRightsReceive-As". After I gave a space "ExtendedRights Receive-As", it works. Thank you.

Just an FYI. ADSIedit works really well too for this if your struggling with the power shell commands. Both accomplish the same thing.
